BACKGROUND Mediterranean societies, with diets rich in vitamin E isoforms, have a lower risk for colon cancer than those of northern Europe and the Americas. Vitamin E rich diets may neutralize free radicals generated by fecal bacteria in the gut and prevent DNA damage, but signal transduction activities can occur independent of the antioxidant function.(More)
BACKGROUND Recent studies suggest that HCV infection is associated with progressive declines in pulmonary function in patients with underlying pulmonary diseases such as asthma and chronic obstructive pulmonary disease. Few molecular studies have addressed the inflammatory aspects of HCV-associated pulmonary disease. Because IL-8 plays a fundamental role in(More)
BACKGROUND Catecholamines, such as epinephrine, are elaborated in stress responses, and mediate vasoconstriction to cause elevation in systemic vascular resistance and blood pressure. Our previous study has shown that IL-1 can induce mast cells to produce proinflammatory cytokines which are involved in atherogenesis. The aim of this study was to determine(More)
Asthma is a chronic inflammatory disease of the airways. Mast cell derived cytokines may mediate both airway inflammation as well as remodeling. It has also been shown that fibroblasts can be the source of proinflammatory cytokines. In the human airways, mast cell-fibroblast interactions may have pivotal effects on modulating inflammation. To study this(More)
Mast cells play pivotal roles in IgE-mediated airway inflammation, expressing interleukin-13 (IL-13) and monocyte chemoattracant protein-1 (MCP-1), which in turn regulate IgE synthesis and/or inflammatory cell recruitment. The molecular effects of interleukin-1 beta (IL-1β) on cytokine expression by human mast cells have not been studied well. In this(More)
